Personnel Safety Features

One of the most important considerations in designing the Cutler-Hammer AMPGARD starter was personnel safety. The result is an extensive system of interlocks and other safety features.

Interlocks

Interlocking on AMPGARD starters includes:

●

Isolating switch mechanism locks the medium voltage door closed when the switch is in the ON position.

●

Provision for optional key interlocks.

●

When door is open, interlock prevents operating handle from being moved inadvertently to ON position.

●

When contactor is energized, isolating switch cannot be opened or closed.

Other Safety Features

AMPGARD starters include many additional features designed to protect operating personnel. These features include:

●

Provision for a padlock on the isolating switch handle in OFF position.

●

Shutter barrier between line terminals and isolation switch stabs is mechanically driven.

●

Distinctive marking on back of switch assembly appears when shutter barrier is in position and starter is completely isolated from the line.

●

Grounding clips provide a positive grounding of the starter and main fuses when the isolating switch is opened.

●

High and low voltage circuits are compartmentalized and isolated from each other.

●

The drawout isolation switch is easily removed by loosening two bolts in the back of the switch. The shutter remains in place when the switch is withdrawn.

Isolation Switch

The Cutler-Hammer Type JMT-4/8, is a drawout, lightweight, 3-pole, manually operated isolating switch mounted in the top of the starter enclosure. It may be easily removed by loosening two bolts in the rear of the switch. The JRM-4 is rated 400 amperes continuous while the JRM-8 is rated 800 amperes continuous. The switches are identical in features and differ only in the current carrying components of the switch.

The component-to-component circuitry concept includes the mountings for the current limiting fuses as part of the isolating switch.

A positive mechanical interlock between the isolating switch handle mechanism and contactor prevents the isolating switch from being opened when the contactor is closed or from being closed if the contactor is closed.

An operating lever in the isolating switch handle mechanism is designed to shear off if the operator uses too much force in trying to open the non-loadbreak isolating switch when the contactor is closed. This feature ensures that the operator cannot open the switch with the main contactor closed, even if excessive force is used on the operating handle.

To operate the isolating switch, the operating handle is moved through a 180º vertical arc from the ON to the OFF position. In the ON position, an operator on the back of the handle housing extends through a bracket on the rear of the starter high voltage door, preventing the door from being opened with the switch closed. When the high voltage door is open, a door interlock prevents the handle from being inadvertently returned to the ON position.

When the operating handle is moved from ON to OFF, copper stabs are withdrawn from incoming line fingers. As the stabs withdraw, they are visible above the top of the fuses when viewed from the front, and simultaneously grounded. As the fingers are withdrawn, a spring-driven isolating shutter moves across the back barrier to prevent front access to the line connections. As the shutter slides into position, distinctive markings appear on the back barrier, making it easier to check the position of the shutter. Refer to

Page 3

Type SL 400 Ampere Vacuum Contactor Bolt-in

FIGURE 1. BOLT-IN CONTACTOR REAR/SIDE VIEW

SL 400 Ampere Vacuum Contactor

Cutler-Hammer Type SL Vacuum Contactors were designed and engineered specifically for use in AMPGARD starters. They are self-supporting, compact, drawout, 3-pole, dc magnet closed contactors. To permit application matching of the starter to the motor rating, the SL Contactor is available in 400 ampere standard and high interrupting ratings.

SL Contactors are available in the standard bolt-in configuration and optional stab-in design. Either bolt-in or stab-in designs can be supplied in a two-high configuration, with a starter maximum of 400 full load amperes. The total structure rating cannot exceed 720 amperes for a combination of two starters.

Design

Cutler-Hammer Vacuum Contactors are highly versatile, low-chop contactors that have been designed to meet all applicable NEMA

�

standards and are UL

�

recognized components. The contactors accommodate mechanical interlocks which function with the starter isolation switch and with other contactors. These interlocks provide unmatched safety and service protection.

The contactors consist of a molded frame with moving armature, magnet and vacuum interrupters. The contactor is easily positioned into the starter and long-life vacuum interrupters provide many operations with a minimal maintenance program. The SL operating coils are energized by a control board which provides a pulse-width-modulated dc output. Control voltages and contactor dropout times are programmed using a DIP switch located on the control board. The control board is mounted in a protected cavity in the molded contactor frame to prevent inadvertent access to the voltage and dropout DIP switch. Four auxiliary contacts (2NO, 2NC) are supplied with each contactor and are wired to terminal blocks on the starter control panel.

The vacuum interrupters employ special main contact materials that exhibit a low chop current plus other specially engineered characteris-tics that minimize switching surges. Surge protection is therefore not required due to the use of the vacuum contactor. Surge protection may be required for other reasons such as the high probability of lightning strike, etc.

Maintenance

Reduced maintenance is one of the outstanding features of the Cutler-Hammer Vacuum Contactor line. The special contact material in the vacuum interrupters provides long life even under severe operating conditions. The main coils operate with a very low temperature rise to maximize insulation life. Steel bearings on the main shaft provide long, trouble-free operation.

A simple go/no-go gauge is used for checking contact wear. Wear can be checked without removing the contactor from the starter. The vacuum contactor is much lighter than previous generation air-break or vacuum contactors, which allows for easier insertion and removal from the starter structure.

Type SL 400 Ampere Vacuum Contactor Stab-in with Wheels, and Line and Load Fingers

400 Ampere Stab-in Contactor

400 Ampere Bolt-in

The bolt-in version of the Cutler-Hammer SL Contactor is supplied as standard for those applications requiring a 400 ampere contac-tor. The contactor is mounted on wheels and rolls into the AMPGARD structure on steel rails. Bolted bus bars connect the contactor line and load terminals to the power components in the starter cell. A 3-phase current transformer, 3-phase potential trans-former and ground fault current transformer are mounted in the cell when required. A plug on the side of the contactor connects the contactor to the low voltage control panel.

The contactor is easily removed from the structure by removing the six bolts securing the contactor line and load terminals, and the pin connecting the isolating switch interlock arm. The contactor can be removed from the starter without disconnecting any medium voltage cables.

400 Ampere Stab-in

A stab-in version of the SL Contactor is an available option. The stab-in contactor is mounted on wheels and rolls into the AMPGARD structure. Contactor line and load fingers engage cell- mounted stabs as the contactor is inserted into the starter cell. The contactor is held in position by a bolt and bracket combination. It can be easily withdrawn from the starter cell by removing the bolt holding the contactor against the bracket and disconnecting the isolation switch interlock. The contactor can be removed from the starter without disconnecting any medium voltage cables.

800 Ampere Vacuum Contactors

The 800 ampere SL Contactor is available in a one-high configuration and is rated at 720 amperes enclosed. The 800 ampere contactor is available with a stab-in type connection only. The 800 ampere contactor is mounted on wheels and has similar features to the stab-in 400 ampere contactor.

Current Limiting Fuses

AMPGARD starters use Cutler-Hammer Type CLS power fuses with special time/current characteristics for motor service. Type CLE or Type HLE power fuses are applied when the starter is used to feed a transformer. The fuse is coordinated with the contactor and overload relay characteristics to provide maximum motor/trans-former utilization and protection. The standard mounting method for power fuses is bolted with an option for fuse clips in the 400 ampere starter. 800 ampere fuses are supplied as bolted only.

Interruption is accomplished without expulsion of gases, noise or moving parts. Type CLS/CLE/HLE fuses are mounted in a vertical position to ensure maximum rating reliability, proper operation and to eliminate the possibility of dust and dirt collecting, resulting in a deterioration of dielectric properties. When a fault has been cleared, a plastic indicator in the top of the fuse, normally depressed, pops up to give visible blown fuse indication. This indi-cator also operates the optional blown fuse mechanism (available with bolted fuses only) on the isolation switch that gives a contact closure to allow use in the starter control circuit.

The control circuit primary fuses are also current limiting.

Blown fuses may be removed and replaced without removing or drawing out the contactor.

Contactor-Fuse Coordination

The AMGARD starter provides ensured coordination between its fuses, contactor, current transformers, protective relays, and the motor it is controlling.

One of the most critical coordination issues is between the contactor and the starter fuses. The fuses must interrupt faults greater than the interrupting rating of the contactor. The AMPGARD 400 ampere high interrupting contactor (SL400A-HI) has an 8-cycle dropout time factory setting as stan-dard and will interrupt at 8500 amperes. The maximum size fuse used with an SL400A-HI contactor is a 450-24R. By comparing the fuse curve with the contactor rating, it can be observed that for faults greater than 8500 amperes, the fuse will open before the contactor. With faults less than 8500 amperes, the contactor may clear the fault before the fuse blows, depending on the settings of the protective relays. Refer to

Figure 3

for an illustration of AMPGARD coordination.

Other vacuum contactors available today may have lower inter-rupting ratings than the AMPGARD Type SL vacuum contactors. Dropout times also vary, and may be as short as two cycles on other starter designs. Lower interrupting ratings and shorter drop-out times can result in fault current levels where the contactor may be required to interrupt a fault greater than its rating. This can result in equipment failure. Refer to

Figure 4

for an illustration of an improperly coordinated starter.

AMPGARD starters also ensure coordination between other starter components. The current transformers and protective relays are selected to work properly with each other, and to protect the motor. Protective relays like the Cutler-Hammer MP-3000 provide optimal motor protection, while also rapidly opening the contactor during fault conditions. This rapid opening signal cannot open the contactor in less than its set dropout time, but it will take the motor off-line in the shortest possible time. This will help minimize mechanical damage to the motor and may prevent the starter fuses from blowing by allowing the contactor to clear the fault (only if the fault is less than the contactor interrupting rating).

AMPGARD starters utilize 400 ampere standard interrupting con-tactors (SL400-SI) when the contactor is not required to coordinate with the starter main fuse. An example of this application is the run contactor of a reduced voltage starter.

Protection Considerations

Coordinated with the motor’s characteristics, the protective devices in the Cutler-Hammer AMPGARD starter provide motor protection from overload to full system capacity faults.

AMPGARD starters are supplied with an adjustable thermal over-load relay as standard. The overload relay is designed to protect the motor from sustained overloads. A Cutler-Hammer Ground-Gard relay is an available option for protection from ground faults. The factory setting for the GroundGard will initiate a starter trip at approximately 7 amperes ground current.

Multi-function solid-state motor protection relays are a common option on AMPGARD starters. The Cutler-Hammer MP-3000 is typically provided when a multi-function relay is specified. The MP-3000 provides many types of protection including overload, locked rotor, ground fault and phase loss/phase unbalance. The MP-3000 also provides start control logic to protect the motor against excessive starting. The relay may be applied to either across-the-line or reduced voltage starters. On reduced voltage starters, the MP-3000 can control the transition from reduced to full voltage, offering the greatest protection for the motor and starter. An optional RTD module can be supplied for motors with built-in RTDs.

MP-3000 Motor Protective Relay

InsulGard relays are an available option on AMPGARD starters. The InsulGard provides early warning of increasing partial dis-charge levels in the starting equipment, cables and motor. This early warning will help the user to better schedule maintenance and avoid unplanned downtime.

Bus and Optional Features

Bus Compartment Top View 3000 A Main Horizontal Bus

Main Bus

When starters are grouped together in a lineup, a typical option is the main bus. The Cutler-Hammer AMPGARD main bus is mounted in its own 12-inch (305 mm) high enclosure, which isolates it from the starter. The connection from the main bus to the starter is done with rigid vertical bus. Insulated barriers are provided for separate top entry of power and control cables. The main bus is top, side and front accessible, which allows for ease of maintenance or extension of lineup without disassembling the starters.

Main bus is available for 1000, 1200, 2000 and 3000 amperes. Main bus is uninsulated as standard. Fully insulated bus is an available option. Bus may be supplied with either tin or silver plat-ing. Crossover bus, busway entry, and pull boxes are not available for the 3000 ampere design (3000 ampere bus duct provisions are available with the Main Breaker AMPGARD, see

Page 17

).

The standard bus short circuit rating is per NEMA standards and is based on the let-through current of the largest fuse used in any starter. An optional 50 kA, 1-second bus rating is available for customers that require a higher rating for the main bus.

Vertical Bus

Vertical bus is located behind a fixed barrier in the rear of the enclosure. It is fully insulated as standard, with plating to match that of the main bus.

UL and CSA Certification

AMPGARD starters are designed, assembled and tested to meet all applicable standards: NEMA/ANSI ICS3, EEMAC E14-1, UL 347 and CSA

�

C22.2 No. 14. The major components i.e., contactor, isolating switch, fuses, MP-3000, IQ DP-4000, and IQ Analyzer are UL recognized.

UL or CSA labeling of a specific starter requires review to ensure that all requested modifications and auxiliary devices meet the appropriate standards. Refer to factory when specified. AMPGARD starters meet the requirements of IEC standards 60694, 60298 and 60470.

Advantages

● Reduces starting currents.● Least costly reduced voltage starting method.

Disadvantages

● Large footprint: 1-1/2 structures at 400 amperes.● “Bump” on transition to full voltage.● Not as efficient as autotransformer.● Due to reduced torque during starting, motor must

typically be unloaded during the start sequence.

Sequence of Operation

● Main contactor (M) closes.● Current flows through reactor reducing voltage to motor

(based on tap setting).● When motor current reaches ~125%, the run contactor

(R) closes providing full voltage to the motor.

Reduced Voltage Autotransformer StarterTABLE 2. TYPE 602 AUTO-TRANSFORMER STARTING CHARACTERISTICS


Auto Transformer Starter

Advantages

● Produces the most torque per incoming line ampere of any reduced voltage starting method.

● Less costly than RVSS.

Disadvantages

● Large footprint: 1-1/2 structures at 400 amperes.● More costly than reactor.● “Bump” on transition to full voltage.● Due to reduced torque during starting, motor must

typically be unloaded during the start sequence.

Sequence of Operation

● Shorting contactor (S) closes.● Main contactor (M) closes.● Current flows through autotransformer reducing voltage to

motor (based on tap setting).● When motor current reaches ~125%, the shorting contactor (S)

opens and the run contactor (R) closes providing full voltage to the motor.

Note: Since the motor is never disconnected from the supply voltage, the starting is closed transition.

1. Industry exclusive integral run contactor dramatically reduces overall size of starter.

2. Run contactor is open, all current passes through the SCRs and voltage is reduced per program requirements.

3. After start is complete, the run contactor closes, then the SCRs are turned off (closed transition).

4. The SCRs are on only a short time therefore no MCC venting or cooling is required.

5. Because the run contactor never sees the in-rush current, it is sized only for full load amperes.

If maintenance or repair of the SCR truck is required, it can be quickly removed and the motor can be started at full voltage by two methods. Method one is to move the lower compartment load cables from the load stabs to the line stabs (see photo). Method two is to install the optional bypass truck.

Synchronous Motor, Brush Type Solid-State Soft Sync Field Control

The synchronous motor starter includes the basic induction motor control in the bottom half of the structure. The synchronous con-trol and protection function fit easily in the upper compartment.

The step down static excitation transformer is connected to the load side of the main contactor and is protected by its own current-limiting fuses.

The static exciter is an SCR type. Its dc voltage output is adjust-able via door-mounted potentiometer. Minimum setting is 50% of rated voltage.

The synchronous control board monitors the induced field during acceleration and energizes the dc rotor field at the optimum speed and rotor-stator pole relationship.

Solid-state, brush-type synchronous motor control includes the following protective features:● Locked rotor protection.● Incomplete sequence.● Failure to synchronize.● Fuse failure.● Pullout protection.● Field loss protection.

The motor windings are protected by the conventional induction motor control protection (thermal, MP-3000).

When ordering you must specify:● dc field amperes.● dc field volts.● Maximum induced field current rms at start (starting and

discharge resistor amperes).● Starting and discharge resistor ohms.

Note: Maximum induced field current multiplied by starting and discharge resistor ohms must be less than 1500 volts to prevent damage to starting equipment and motor.

Synchronous Motor, Brushless ECS/VR Field Controller

The brushless synchronous motor starter includes the basic induc-tion motor control in the bottom half of the structure. The ECS/VR synchronous control and protection module fits easily into the upper compartment.

The step down excitation transformer is connected to the load side of the main contactor and is protected by its own current-limiting fuses.

The ECS/VR uses IGBT technology to control the dc output. The field voltage level can be adjusted from the HMI. The output is adjustable across the full range 0 – 150 Vdc.

The ECS/VR applies field voltage after an adjustable time delay. The controller monitors the stator current and voltage levels for metering and protection purposes. Automatic power factor regulation is an available option.

The ECS/VR brushless motor control includes the following protective features:● Incomplete sequence.● Failure to synchronize.● Pullout protection.● Field loss protection.● Over excitation.

The motor windings are protected by a motor protection relay such as the MP-3000.

When ordering you must specify:● dc field amperes.● dc field voltage.● Complete motor data sheet is preferred.

Incoming Line

Depending on the size and number of incoming cables, an incom-ing line enclosure may be necessary. Different designs are avail-able for incoming power for top or bottom entry.

The addition of incoming line metering requires a 36-inch (914 mm) wide structure in lieu of a 24-inch (610 mm) wide structure.

Typical 24-Inch (610 mm) Wide Incoming Line Structure

Bus for Top or Bottom Entry Incoming Power

Potential Transformers, Control Power Transformer Disconnect and Fuses

Bus connected potential trans-formers and/or control power transformers are mounted in a 20 inch (508 mm) high assem-bly that includes a disconnect and primary fuses. The assem-bly can be mounted in a 24 inch (610 mm) or 36 inch (914 mm) wide structure.

Type LBS Loadbreak Switch

For application needs with loads rated 600 or 1200 amperes at 2300 to 6600 volts, AMPGARD is available with the Type LBS loadbreak switch. This device, a 3-pole, manually operated, quick-make, quick-break switch, is used primarily as a disconnect switch in ac power systems. This switch is fixed mounted and will fit in one-half of a standard 80-inch (2032 mm) high, 36-inch (914 mm) wide vertical structure. Power fuses up to 450E amperes can be mounted within the half-high structure. 600E or 750E fuses require an additional half-structure, 1100E or 1350E fuses require an addi-tional full structure. Mechani-cal interlocks are incorporated so that the door cannot be opened when the switch is on, and when the door is open the switch cannot be closed. A safety screen is supplied behind the switch door. The Type LBS switch can be supplied with a total of four electrical interlocks.

Main Breaker AMPGARD — Doors Open


Requires Less Floor Space

● Only 60 inches (1524 mm) deep, the integrated MBA design provides a bus system that directly connects to AMPGARD motor starters, eliminating space-consuming transition sections. The reduced floor space requirements yield significant cost savings, particularly when installation in a prefabricated electrical house is required.

● Back-to-back design provides for an increase in the number of starters without an increase in floor space.

Front/Side Accessible Connections

● All connections requiring maintenance are front or side accessible.

● Rear access space is not required.● An MBA (excluding back-to-back design) can be installed flush

against the wall.
